Ⅲ. Advantages

1. Uniform Formation: The air cushion headbox provides consistent and uniform distribution of the paper pulp across the width of the forming wire. This helps achieve a uniform basis weight and formation, resulting in improved paper quality with fewer defects.
2. Reduced Fiber Orientation: The use of an air cushion helps reduce the orientation of paper fibers in the machine direction, leading to improved sheet isotropy (uniformity) and better strength properties in both the machine direction and cross direction.
3. Enhanced Sheet Properties: By promoting more even fiber distribution, the air cushion headbox can contribute to better paper strength, formation, and surface properties, ultimately leading to improved printability, smoothness, and uniformity.
4. Increased Production Speed: The controlled air cushion allows for higher machine speeds while maintaining paper quality. This can lead to increased production rates and higher overall machine efficiency.
5. Reduced Headbox Jet Impact: Traditional headboxes use hydraulic pressure to distribute pulp, which can cause high jet impact on the forming wire. The air cushion headbox produces a gentler and more controlled distribution, reducing the risk of wire wear and damage.
6. Reduced Energy Consumption: The air cushion headbox requires less energy compared to some traditional headbox designs, as it operates at lower pressures and doesn't rely on hydraulic systems for pulp distribution.
7. Improved Formation Control: The air cushion headbox allows for precise control of the pulp jet trajectory and distribution angle, contributing to better control over sheet formation and basis weight profiles.
8. Versatility: Air cushion headboxes can handle a wide range of basis weights and furnish types, making them suitable for various paper grades and applications.
9. Minimized Pulp Froth: The controlled air cushion can help prevent excessive frothing of the pulp, which can be an issue with certain types of paper stock.
10. Less Water Consumption: The efficient and controlled distribution of pulp achieved by the air cushion headbox can lead to reduced water consumption during the papermaking process.
11. Quick Start-up and Changes: Air cushion headboxes are often designed for easy adjustments and quick start-ups, allowing for faster grade changes and reduced downtime during production transitions.
12. Improved Formation Flexibility: The air cushion headbox's adjustable air layer thickness allows for flexibility in controlling sheet formation characteristics, contributing to the ability to produce various paper grades with desired properties.
